Type
Half bridge 3 source pin. This pin must be connected together with
pin SENSE
this pin also the inverting input of the sense comparator is
connected.
Selects the direction of the rotation. High logic level sets forward
operation, whereas low logic level sets reverse operation. If not
used, it must be connected to GND or +5 V.
Chip enable. Low logic level switches off all power MOSFETs. If not
used, it must be connected to +5 V.
Current controller reference voltage. Do not leave this pin open or
connect to GND.
Brake input pin. Low logic level switches on all high-side power
MOSFETs, implementing the brake function. If not used, it must be
connected to +5 V.
Output 3.
Half bridge 3 power supply voltage. It must be connected to the
supply voltage together with pin VS
Half bridge 1 and half bridge 2 power supply voltage. It must be
connected to the supply voltage together with pin VS
Output 2.
Charge pump oscillator output.
Single ended Hall effect sensor input 2.
